'Astronomers might have found something regarding the Milky Way that could change everything they know so far about its formation.Experts believe that they have been able to map an important sequence of events that has shaped our galaxy 10 billion years ago.A recent paper that’s been published in   Nature Astronomy,  researchers from the Instituto de Astrofisica de Canarias (IAC) shared their discovery that a dwarf galaxy, Gaia-Enceladus, once collided and merged with the early Milky Way.Their discovery offers a brand new understanding of how the Milky Way has formed.Astronomers used to believe that the galaxy has been made of two separate sets of stars, but the way when these two came together or when this happened was still a mystery.Now, with the help of the Gaia space telescope, researchers have been able to make some more precise measurements on the position, brightness, and distance of one million stars.The evidence of a galaxy collision pops up Experts were also able to check out the density of metals or elements without helium and hydrogen that the stars contain, Engadget notes.They found that both sets of stars are about the same age but one was set into “chaotic motion” as the online publication puts it.This was the evidence of a galaxy collision.Engadget notes that “The researchers believe Gaia-Enceladus collided with the young Milky Way about 10 billion years ago, and over the course of millions of years, the Milky Way consumed the dwarf galaxy.” Researchers said that this new info brings details without precedent about the early stages of your cosmic history.Anyway, just in case you didn’t know, this is not the first time experts talked about one galaxy consuming another.For instance, Andromeda has “cannibalized” a nearby galaxy and this happened about 2 billion years ago. .

'NASA and ESA have been hard at work in the recent months, and the two agencies have created a new strategy for the lunar Gateway project which focuses on the trajectory that could be pursued by the outpost during orbit.They decided to select a near-rectilinear halo orbit.The choice makes a lot of chance since the highly elliptical path should remove a lot of problems while also facilitating specific tasks.It will be easier for astronauts to participate in missions connected to the lunar surfaces, and the difficulty of bringing new supplies to the outpost will be decreased.The team who devised the mission planners spends a considerable amount on time weighing the advantages and disadvantages of different orbits.The near-rectilinear halo orbit, also known as the NRHA was selected.At first sight, it may not appear to an important decision, but it plays an essential role in the development of the Gateway Project.NASA and ESA are working on strategies for the Gateway lunar outpost The NASA and ESA may spearhead the initiative, but a lot of institutions contribute to the project, including the Canadian Space Agency, Roscosmos, the Japanese Space Agency (JAXA) and other partners.It is estimated that the middle of the 2020s will build the outpost.The primary purpose of the outpost is the use it is a starting zone for crewed missions to the moon and other objectives.The upcoming Artemis initiative will benefit significantly from the project, as it aims to send a crew of astronauts on the surface of or natural satellite by 2024.Among the facilities which will be offered by the Gateway Project, we can count the inclusion a laboratory, a depot where valuable resources can be stocked, a communications hub and a dispatch area for a large number of secondary goals.The Artemis project requirements specify that THE Gateway has to be placed at a specific distance from the moon and Earth to maximize its potential and utility in the long-run. .
